The device can, in theory, work anywhere in the world the device has a line-of-sight to a Globalstar satellite. In practice, reviewers have found this to be largely true. However, placing the device in a pocket, vehicle, under tree cover, or among tall buildings may prevent a message from being received. The device will repeat transmission of its emergency messages at predefined interval until the user cancels the emergency, turns off the device, or until the batteries run out. SPOT's transmission ability is one-way only so the device is unable to give the user confirmation that a message was successfully sent.
Satellite phones will work if you're in Death Valley. Height means nothing.Hungry Seagull said:A satellite phone might do it if you can gain enough height.
That is a big risk there.However, placing the device in a pocket, vehicle, under tree cover, or among tall buildings may prevent a message from being received.
I believe you are mis-understanding this thread.Hungry Seagull said:nalioth, Ive been through the Humdolt and Death Valley many times ...
Many loads to various parts of Nevada towards Reno. Great desolation. Satellite comms have never failed me in all that time via Qualcomm in the truck.
If you can stay consious and alert when over 12,000-15,000 feet then you can talk to me about height.
Height has nothing to do with satellite based communications, but is more related to radio frequency communication (getting a good line of sight from higher up, etc). All one needs for satellite commo is an unobstructed sky.A satellite phone might do it if you can gain enough height.
